– “New Zealand […] put in travel restrictions almost before COVID-19 was officially known about, but any delay in the spread of a virus […] ends once the restrictions are lifted, even if they work anyway.”
See the article SA linked for you; restrictions were mostly lifted on May 14. And they had worked, in New Zealand’s winter; New Zealand had 2,181 cases and 25 deaths. New Zealand has wiped out covid-19 twice.
